Abstract

Optoelectronic systems include an array of optoelectronic modules and a computational unit. The array of optoelectronic modules and the computational unit are operable to collect data of a user of the optoelectronic system. The data can be used, for example, to authenticate the identity of the user by being used in multiple user authentication protocols. In some instances, facial recognition data can be augmented with three-dimensional data of the user and can be combined with iris recognition data to authenticate the identity of the user. Such optoelectronic systems can comprise hardware authentication systems external to auxiliary devices such as tablet computers and laptop computers.
